Overview
The BV042-5196.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a single primary winding rated at 230V and a single secondary winding providing 15V at full load with a maximum current of 334mA. The unit has a maximum power rating of 5VA and utilizes PC pin termination. Physical dimensions are 45.50mm in length and 38.50mm in width, with a maximum installation height of 32.00mm. The component weighs approximately 60.33g and operates without a center tap.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Single primary to single secondary winding configuration
- Through-hole mounting with PC pin termination
Applications
- Switching power supply transformers
- SMPS (Switched-Mode Power Supply) applications
Procurement Notes
Verify the specific datasheet version, as documentation references may vary between EI42 and other core types. Confirm that the 15V secondary specification aligns with design requirements, noting potential discrepancies in third-party listings. Check lifecycle status, as some sources indicate discontinued status while others list it as new. Ensure through-hole compatibility with PCB layout constraints regarding the 32.00mm height limit.
Selection Notes
Select this component when a 5VA isolated transformer with 230V primary input is required. The 15V secondary output suits low-power control circuits or bias supplies. Verify that the laminated core type meets EMI/EMC requirements compared to ferrite alternatives. Ensure the through-hole package fits the assembly process and mechanical envelope constraints.
Part Context
This part belongs to the Pulse Electronics BV042 series of power transformers. These components are engineered for general-purpose isolation in AC-DC conversion stages. The series typically offers various voltage configurations while maintaining consistent physical footprints for board design flexibility.
Replacement Considerations
Cross-reference with BV042-5199.0 if an 18V secondary output is acceptable instead of 15V. Both share similar core types and mounting styles but differ in secondary voltage ratings.
